It possibly has to do with loading down the CAN cable driver. I think the total cable length is something like 20' if I remember right. One suggestion was to buy a 20' cable and use it. If you need more, you've used too much.

Read joystick should probably go in Periodic. Continuous will read the joystick as fast as possible. Periodic will read the joystick at precise intervals (200Hz I think). Honestly, in reference to the system response time of "Joystick moved -> Joystick value read -> Joystick value interpreted -> Motor value sent -> Motor starts moving", the moving of the motor is the longest part (by quite a bit).

Running in continuous only makes more requests and sends more control packets (unnecessarily) utilizing more system bandwidth.
